What's My Line At 25: A retrospective of the classic game show, What's My Line, in which a four-member celebrity panel attempted to identify a contestant's occupation through yes or no questions. In addition, each episode featured a celebrity mystery guest that the panelists tried to identify the guest while blindfolded. The show ran from 1950-1967 and prominently featured John Daly, Bennett Cerf, Arlene Francis, and Dorothy Kilgallen. This documentary looked back on the show 25 years after it premiered.
